CRAWLSPACE MOISTURE

CRAWLSPACE MOISTURE PROBLEMS

It is not enough to install more crawlspace vents, because vents can actually
trap more moisture into the crawlspace if they are not

According to an Advanced Energy study, implementing additional ventilation
causes higher relative humidity levels, as well as ways for energy to
escape. Plus, it exposes your home to pests, bugs, and bacteria. This
study shows consistent evidence that insulated crawlspaces work better
than ventilated crawlspaces.

HERE ARE THE MOST IMPORTANT FINDINGS FROM THE STUDY ON CRAWLSPACE MOISTURE PROBLEMS:

Crawlspace encapsulation, wood rot and moisture stay below 12%.

Insulated crawlspaces are significantly dryer than crawlspaces with lots of vents.

When tested in a dryer climate, the sealed crawl spaces controlled normal
moisture levels (around 50%); yet the vented crawl spaces kept 70% relative
humidity for a only a few days.
